Getting around the Cotswolds is best done by car. If you don't have your own vehicle, you can rent one easily from a number of car rental companies. You can also opt for public transportation, including buses and trains, but it's important to check schedules and routes ahead of time. Expect to spend around £45-£60 per day to rent a car, and travel times can vary greatly depending on traffic and routes chosen.
If you have extra time, consider visiting the Bath Aqua Glass studio to learn the ancient craft of glass-blowing or head to Tetbury to explore the boutiques and antique shops. For a shorter itinerary, consider visiting just Bourton-On-The-Water and the stunning Painswick Rococo Garden, followed by a day exploring Blenheim Palace, and finish with a day trip to Sudeley Castle and Stow-on-the-Wold.
